Police said 39-year-old Delvin Johnson was dead when officers arrived, and 59-year-old Earl Clark -- along with Allen -- was taken to University of Mississippi Medical Center, where both men were treated for what police said are non-life-threatening injuries.

Tonia Gathings said her niece was inside the house when someone shot and killed her boyfriend.

"She said, 'I just called 911 and (police) are here.' She said, 'But I tried to give him CPR.' She just broke down and dropped the phone and that was the end of the conversation," Gathings said. "I was speechless. I couldn't believe it."

Neighbors said Johnson has several children, one of whom showed up at the scene after she heard about her father's death.

"Everybody has a little difficulties in their lives, but other than that, he was trying to get it together. Overall, to me, he was an outstanding guy," said Johnson's friend, Shonda Robinson.

Police are not sure what led to the shooting.

"It's still under investigation," said Cmdr. Tyree Jones. "We still don't have a motive or what exactly happened. We're still in the preliminary stages."
